Public bug reported: I have an Acer V5-573G which fails to resume from suspend for all kernels past 3.14.51 (I've tested 4.2.0-040200 and it still doesn't resume). When attempting to resume, the hard drive spins up, the keyboard backlight turns on, the suspend light goes from orange to blue, but the screen stays resolutely black and the only keypress it seems to recognise is alt-sysrq-b.
I think this is a duplicate of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1416557 (where I've left more information) and https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1429347 and https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1389202. I suspect that the resume problem has something to do with the changes made in https://01.org/suspendresume/blogs/tebrandt/2013/hard-disk- resume-optimization-simpler-approach. These were made between 3.14.51 and 3.15.0-RC1, I think.
